SMAP Validation Experiment in 2022 (SMAPVEX22) takes place in April, July, and August over Harvard forest in Massachusetts and Milbrook in New York. The science objective is to improve and validate soil moisture retrieval algorithms over forest regions. Due to the scattering and absorption effects by the thick vegetation, forest regions are one of the most challenging targets for soil moisture retrieval. Yet carbon science, forest fire, and other applications require reliable information on soil moisture. This campaign will contribute to the science goals of NASA's SMAP and NISAR missions. SMAPVEX22 include the following components of observations: SMAP satellite data, PALS (Passive Active L and S band) airborne data, L-band UAVSAR data, upward looking ground radiometer, upward looking Lidar, mobile receiver for bistatic observations of GPS signal, detailed characterization of vegetation geometry and water content, soil surface roughness, and soil moisture.
